Expression and prognostic value of brain and acute leukemia cytoplasmic in meningiomas

摘要

Meningiomas are the most common central nervous system neoplasms. The World Health Organization (WHO) 2016 classification system classifies meningiomas into three grades: grade I (benign), grade II (atypical), and grade III (anaplastic/malignant) meningioma. Benign meningiomas are usually associated with favorable prognosis; however, higher grade (WHO grades II and III) menigiomas are more aggressive, resulting in less favorable outcome.
